For those who wish to later upgrade to any RAID capabilities a system with Areca online RAID level stripe size migration allows a simplified upgrade to any supported RAID level without having to reinstall the operating system The SAS RAID controllers can migrate both the RAID level and stripe size of an existing volume set while the server is on line and the volume set is in use Online RAID level stripe size migration can prove helpful during performance tuning activities as well as when additional physical disks are added to the SAS RAID controller For example in a system using two drives in RAID level 1 it is possible to add a single drive and add capac ity and retain fault tolerance Normally expanding a RAID level 1 array would require the addition of two disks A third disk can be added to the existing RAID logical drive and the volume set can then be migrated from RAID level 1 to 5 The result would be parity fault tolerance and double the available capacity without taking the system down A forth disk could be added to migrate to RAID level 6 It is only possible to migrate to a higher RAID level by adding a disk disks in an existing array can t be reconfigured for a higher RAID level without adding a disk Online migration is only permitted to begin if all volumes to be migrated are in the normal mode During the migration process the volume sets being migrated are accessed by the host sys tem In addition the volume sets wi
